It's really hard to get good gas mileage from a mustang. There area few things you can do to improve it 1-3mpg but its not that much.
3) If the car hasnt ever been seafoamed I'd suggest buying some seafoam. It works wonders and really cleans up the engine. There are lots of threads on here about seafoam.
Seafoam is gods gift to cars!!
